The 'Criminal' singer is preparing for the launch of the show's second season next month, after being announced alongside Demi Lovato as the series' two newest additions back in May.

Britney poses in a short black dress in the new promo alongside actress and singer Demi, who also wears a black dress with a white jacket over the top.

The advert was unveiled at the same time as a brand new TV advert showcasing some of the contestants viewers can expect to see on the new season, with scenes of one woman being wheeled out of the auditions on a stitcher hinting at high drama to come.

"Ahh! This gave me chills, looove the contestants," Britney tweeted alongside a link to the trailer. "Can't wait to see the first episode of @TheXFactorUSA!"
